Gaudy

Gaudy is an adjective that is used to describe being extravagantly bright or showy, typically so as to be tasteless. Flashy. Garish.

Examples:

They purchased the most ‘gaudy’ car that was available at the time, just to show to people that they had wealth. However, they soon came to realize that none really cared because people were too busy living their own lives.

She walked into her family gathering in the most ‘gaudy’ clothes that were living in her closet.. Her family just made humorous jokes just like she expected.

Living a ‘gaudy’ lifestyle can lead to unnecessary things being purchased, whereas if you live a simple life you can get rid of all the distraction and focus on that which is important.
